Liquid-droplet ejecting apparatus, method for controlling the same, and nonvolatile storage medium storing program for controlling the apparatus

Abstract

A liquid-droplet ejecting apparatus including: a head configured to eject liquid onto a recording medium; a curl-amount calculating section configured to calculate a curl amount of the recording medium on the basis of a location of at least one evaluation region on the recording medium and calculated amount of the liquid and the calculated number of liquid droplets to be ejected for the at least one evaluation region; and a curl suppressing section configured to change the evaluation ejection data for the at least one evaluation region on the basis of the calculated curl amount of the recording medium so as to change the amount of the liquid and / or the number of the liquid droplets to be ejected onto at least the at least one evaluation region on the recording medium to suppress the curl of the recording medium.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority from Japanese Patent Application No. 2011-018736, which was filed on Jan. 31, 2011, the disclosure of which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a liquid-droplet ejecting apparatus configured to eject droplets of liquid such as ink to form an image on a recording medium, a method for controlling the apparatus, and a nonvolatile storage medium storing a program for controlling the apparatus, and more particularly to a technique for suppressing a curl of the recording medium on which the liquid is attached.[0004]2. Description of the Related Art[0005]As one example of a liquid-droplet ejecting apparatus, there is known an ink jet printer configured to eject ink onto a recording medium such as a paper sheet, a cloth, and a film to record or form an image thereon. Water-based ink containing wat...

AI Technical Summary

Benefits of technology

[0007]This invention has been developed in view of the above-described situations, and it is an object of the present invention to provide: a liquid-droplet ejecting apparatus configured to accurately and speedily estimate an amount of a curl of a recording medium on which an image is formed, on the basis of the above-described findings, and to prevent the curl while suppressing a lowering of a throughput of recording on the basis of the estimated amount of the curl; a method for controlling the apparatus; and a nonvolatile storage medium storing a program for controlling the apparatus.

Problems solved by technology

Accordingly, the method in the above-described proposal does not always estimate the amount of the curl of the recording medium accurately.

If the estimate amount of the curl of the recording medium is not accurate, when the curl is corrected on the basis of this estimated amount, the correction may be not enough, and a greater length of time and / or a greater amount of energy than necessary may be required for the correction.
